SPECIFICATION forming part of Letters Patent No. 441,667, dated December 2, 1890.

Application filed August 25, 1890- Serial No. 362,964. No model.)

' fication, reference being had therein to the accompanying drawings.

This our inventionvrelates to strainers applied to water feeding or distributing pipes for separating and collecting therein all more bulky impurities contained in the water; and it has for its object to provide a chamberpiece that may be coupled between two pipesections or anywhere to or between the water-course, the same to have inserted a basketstrainer, through which ,all the water must pass, for detaining therein all such impurities, and which can be readily removed for emptying and cleaning it from time to time of all impurities collected therein and with these objects in view our invention consists of the novel devices and combinations of devices hereinafter described and specifically claimed.

In the accompanying drawings, Figure 1 represents a longitudinal vertical section through the center of the strainer; Fig. 2, an exterior view of the same, and Fig. 3 an elevation of the basket-strainer detached.

Corresponding letters of reference in the several figures of the drawings designate like parts.

A denotes the casing, being a cylindrical chamber provided on diametrically-opposite sides with screw-nozzles a and b for connecting the pipe-sections, the one a for water to enter and the one I) for water to escape. These screw-nozzles a and I) being near one end of the cylindrical chamber A, said cham-' ber is divided interiorly by a diaphragm c, the nozzle a communicating with the chamber above such diaphragm c -and the nozzle b communicating with the chamber below E, made of thin finely-perforated metal, with a perforated bottom, is of a diameter to enter the bore of diaphragm c, and hasa collar or flange e to its upper end, that will provide a seat or shoulder to the upper face of diaphragm c. This collar or flange e has'to its diametrically-opposite upper edges two ears f, connected by'a cross-rod that forms a handle on which to lift the strainer-basket out of the casing A after removing the screwplug cl. When the strainer-basket E is inserted into the casing A and the screw-plug d has been secured, the upperends of ears f will butt against the lower rim of the screwplug, thereby holding the collar or flange e rigidly to bear upon the upper face of the diaphragm c. The strainer-basket E is also provided at its lower end with two or more foot-lugs h, that will rest upon the bottom of the chamber of easing A for providing an additional support to such strainer-basket E and release the collar or flange e of part of the strain caused by the resistance to the water with passing through the perforations in such strainer-basket, particularly after impurities have accumulated therein.

Itwill be readilyseen that the waterenterin g through nozzle a will first enter the strainerbasket E and must pass through the perforations thereof before it can escape through nozzle b, whereby all impurities larger than the perforations will be detained in such strainer-basket E, which from time to time can be removed by unscrewing the screwplug cl and then lifting out the strainer basket, to be readily replaced after cleaning it. This removal and cleaning must of course be attended to during the time the flow of water has been stopped. I

The casing A may be made of any desired length for the desired length of strainerbasket E. It is generally calculated that the total area of all the perforations therein is six times the area of the water inlet or outlet through nozzles a, and b, so that such strainerbasket will not readily be choked, but that even with being nearly filled with impurities still sufficient openings will be left for the volume of water to. pass through the same without perceptible obstruction.

This strainer may be connected either to the suction-pipe or to the discharge-pipe of a pump or anywhere to a distributing-pipe in a position where it can be readily reached for frequent removal and cleaning of the strainerbasket.

What I claim is- 1. The combination, with a cylindrical casing having on diametrically-opposite sides a waterinlet and an outlet nozzle separated by a diaphragm and a screw-plug to one end, of a strainer-basket removably inserted through the screw-plug opening and through the bore of the diaphragm and having a flange or 001- lar 6, with ears f, providing bearing-shoulders against the diaphragm and under the screw-plug, substantially as set forth.

2. The combination, with casing A, having OMAR H. JEWELL.
